TLDR: NEW YORKâFederal prosecutors say Google engineer Michele Spagnuolo used internal Year in Search data to win $1.2 million on Polymarket, allegedly via âAlphaRaccoon.â
Key Takeaways:
- Michele Spagnuolo, a Google employee for 12 years, allegedly used internal âGoogle Confidentialâ search tool data to guide Polymarket bets.
- Prosecutors say he deployed a crypto wallet with $2.7 million across dozens of contracts, including Bianca Censori and Pope Leo XIV not topping searches.
- If convicted on commodities fraud, wire fraud, and money laundering, he could face up to 50 years, signaling tougher DOJ scrutiny for prediction markets.
A prediction market was built for odds, not employee logins. The DOJ case turns âharmless forecastingâ into a very expensive lesson in where information should stay.

Q&A
How might DOJ prove the line between âusing publicly known oddsâ and âusing internal referencesâ in a market like Polymarket?
Prosecutors typically rely on system access records, timing of bets after tool queries, and evidence that internal fields were not otherwise available publicly.
What incentives does the setup create for other employees at big tech firms with marketing dashboards and analytics tools?
If insiders believe they can translate internal metrics into faster, more accurate bets, the temptation spikes, and that is exactly what regulators try to deter.
Why does the complaint lean on one marketing campaign, and what does that choice suggest about the strength of the evidence?
Targeting one concrete dataset like âGoogle 2025 Year in Searchâ can create a clear match between internal signals and specific contracts, tightening the narrative.
If Polymarket keeps operating globally, what changes in its risk posture when U.S. insider trading cases succeed in court?
It may harden compliance, expand monitoring, and cooperate more aggressively, because even one case can trigger deeper platform wide scrutiny.
What is the bigger precedent here for other âevent contractâ platforms dealing in real world outcomes?
The theory is transferable: when internal material nonpublic information can drive market advantage, prosecutors may treat prediction trading like a fraud and trading integrity problem.
